i INTERNAL-COMBUSTION ENGINE.

Be it known that I, Hnnnox B. a citizen'of-the United States, and residing 'at New York, in, the county of New York and Stateof'New Yorlnhave invented certain .-.new andus eful Improvements in Internal- Combustion Engines, of which the following is a specification, such as will enable apper-.

those skilled in the art to which it tains to make and use. the same. g This invention relates to explosion or internal combustion engines, and particularly to engines of this classof the sleei e valve type, and the object'thereof is to improve the construction of, and the method of assembling the parts of, engines of this class,

so as to facilitate the finishing and assemblin of said arts and render the same more practical and economical and at the same time increase the efficiency of such engines;

and with this and other objects in vicwtheinvention consists in the construction, combination and arrangement of after described and claimed.

This invention is'applicable to engines of the class specified, comprising any desired number of units or cylinders, and said invention is fully disclosed in the following specification, ofxwhich the accompanying drawing forms a part, in which the separate parts of my improvement are designated b suitable reference characters in each of the views, said drawing-being a central vertical transverse section through one cylinder of 'In carry ng my lnvention into effect, I provide a cylinder a, the top portion. of

which is inclosed' by a casing 7) into which :the cylinder is inserted from the bottom thereof, and said casing 7) is inclosed by a Q supplementalcasing or jacket b -which is formed integrally therewith and which also incloses the inlet andexhaust manifolds 0 and d, and the bottom of the casing" 7) is provided with an outwardly directed flange orrim b.

The top of the cylinder ais contracted to.

' form an inwardly directed'annular and upwardly inclined wall or shoulder 11 having a neck portion a which-forms the bottompart of the explosion chamber, as hereinafter described, and said part a? is provided ."at the top thereof with an outwardly directed, horizontal rim portion at having aspecification of Letters Patent. i Patented partshereim downwardly directed skirt portion apro vided at the bottom with an outwardly directed flangca. which is above the top of the working portion of the cylinder and on which thebottomflange or rim 7f of the casing 7) rests, and between said flange 7)? involves a main outer cylindrical casing-e and which is inserted into the casing 7) from earns TENT, OFF -f,

Oct. 30, 1911); Application filed n11 13,1914..- :SerialNo.'850,5'55.- v f the top thereof. and between which and said casing7 is a sleeve valve chamber 7 in which is'placed alsleeve valve f and thesleeve valve chamber extends from the top -of'the parts 7) and (l -to the bottom of the part 7),

and the outer wall of the-sleeve valve chainbcr is formed by the part 7), while the inner, wall thereof is formed by the part 6 and the skirt of at the top of the cylinder.

The explosion head 6 isprovide d at the top thereof with an overlapping or cap portion a forming a water'chamber "7t in the top portion of said explosion head, and

within said explosion head is another water chamber if, and between the outer casing members 7) and b is another water chamber h which incloses the inletand exhaust manifolds c and (7' and extend downwardly and i'ncloses the top portion of the cylinder in,

the -.usnal, manner, and the water chamber 71 the top portion 'of which incloscs the I I explosion head m-is placed in communication with the water chamber h in the top of said explosion head by ports or passages efl Within the central top portion of the explosion head cis a' cup-shaped chamber 6 which. opens upwardly and in the central bottom portion thereof is another chamberc" which communicates with the neck portion 11; of the cylinder 1;,- and which ,forms in connection with said neck portion of the cylinder the explosion chamber with which the inlet and exhaust manifolds and (l are placed in communication .by ports or passages c" and (7 in the casing member 7), and corresponding radial ports or passages i formed in and between the bottom of the explosion head 6 and the top portion a of the necka of thecylinder, and which extend through the/casing mGfimOI' e? of the 'explosion head;

I The chamber e in the top portion of the explosion head, and the chamber fe r in the bottom portion thereof and which forms a part of the explosion chamber are separated by a central neck portion or' partition 'e having-a threaded aperture e" into which, In practlce, the sparking-plug is screwed in the usual manner, and around the neck po'r .tion a of the cylinder, or between said neck 7 portion and the ,skirt member a is. an annular Water space or chamber h which communicates with the water chamber b around the cylinder, and which also communicates with the water chamber h in the explosion head, the water being free to pass upwardly between the radial .ports or passages i, and

with this construction thereis a continuous flow of water from the" radiatonu'pwardly aroundthe cylinder through'the explosionhead and on the inner side of the valve chamber, or the inner. wall thereof, and around the inlet and exhaust manifolds 0 and d, and around the outer wall of the valve chamber up into the capportion or part c of the explosion head from which the water passes back to'the radiator in the usual manner.

In the accompanying drawing, I have shown no means for operating the valve, but it will beunde'rstood that said valve may be operated in the usual manner, or by any preferred means, such, for instance, as that shown and described in IR S. Letters Patent No. 1,063,082, of Ma 2-7, 1913,01? NO. 1,017,-

073' of February'13, 1912.' 4 It must also be understood thatthe. exploslon head '6, orthe bottom thereof, abuts on or against the top of the neck a of the cylinder, as'shown at g,'and this connection between said parts may be packed in any desired manner. Y i

The main feature of my improvement is found in'the fact that thecylinder is open at the top and, is adapted to be passed upwardly into the casing member 5, .While the explosion head a is passed downwardly into the casing member 6 and the, valve'chamber,

- or the wallsthereof, are formed by the ex plosion head, or the casing member e there of, and the skirt member a at the top of the cylinder and the main outer casing: member I) and, as will be understood, this construc tion facilitates the formation of all of the said parts, and the machining and finishing of the valve chamber and the'connection of the various parts, and renders the said operation or operations more simple andelfective and at the same time more economical than is usual in this class of devices.

Having fully described my invention, what I claim as new and desire to. secure by Letters Patent,is:--

1 In an explosion engine, a main cylindrical casing, acylinder the top portion of which isjnsertible into the bottom of s id casingfand. an explosion hea'd member in sertible into the top portion of said casing,

2. In an explosion engine,,a main cylindrical casing, a cylinder the top of which is explosion head which. isins'erted into the top portion of'said casing, a sleeve valve chaminserted into the bottom of said casing, an'

ber formed between said casing and the ex plosion head, and the top part of the cylinder, and an explosion chamber formed partly in the top of the cylinder and partly in the explosion head and provided with radial said casing, an explosion head inserted into the top portion of said casing andpro'vid'ed witha cap,' a sleeve valve chamber formed between said'casing and the explosion head and the top' portion of the cylinder, an ex plosion chamber formed partly in the ex-,

plosionxhead and provided with radial ports or passages which communicate with inlet and exhaust manifolds, and means whereby the water may be circulated upwardly around the cylinder and on the outer slde of said casing and between the explosion chamber and the sleeve valve chamber and'into the cap of the explosion head.

4. In an explosion engine. a main cylindri-r cal casing having inlet and exhaust manifolds, a cylinder the top of which is in serted into the bottom portion of said casing, and an explosion head inserted into the top portion of said casing, the explosion chamber-being formed partly in the top portion of the cylinder and partly in the explosion head,and means whereby water may-be cir-1 culated upwardly and continuously through. the explosion hid and between the explosion chamber and valve chamber'.-

'5. In an explosion engine,'a mam cylindrical casing havinginlet and exhaust manifolds, a cylinder the top of which is inserted into the bottom portion of said casing, and

an explosion head inserted into the top portion, of said casing, the explosion chamber being formed partly in the top portionpf the cylinder and partly 1n the explosion head, and means whereby Water may be circulated upwardly and continuously through the'ex-plosion head and between the explosion -chamber and valve chamber and on the outer side of said valve chamber.
